Genes affected

POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.6004+5G>T variant in POLE has not been previously reported in individuals with colorectal cancer but has been identified in 22/65018 of European chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP rs372169366). This variant is located in the 5' splice region. Although nucl eotide substitutions at +5 position of the intron are relatively common causes o f aberrant splicing, computational tools do not suggest an impact to splicing. H owever, this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the c.6004+5G>T variant is uncertain. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
